AHU cleaning in Twineham Green
We clean air handling units for buildings in Twineham Green and across West Sussex, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers filter sections, internal panels and heating and cooling coils, and common reasons people get in touch are dirty fans and fan housings and rooms that smell stuffy when the system runs.
Work in a small place like Twineham Green starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Each visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How we price AHU cleaning
The diagnosis comes before the price. The main factors are:
- Whether it’s a one-off visit or part of a schedule
- When the work can happen, such as evenings, overnight or weekends
- How big the system is
- How easy every part is to reach
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before work begins.
What to send for a quote
When you call or email, these details help:
- Any previous report or certificate
- Close-ups of filters, grilles, hatches or access panels
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
For AHU cleaning in Twineham Green, call us on 0345 646 2711, or send details by email. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. We typically send a fixed quote within one working day.
The process
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes from a few hours for a compact unit to a day or more for a large one. If you can send photos, we can arrive in Twineham Green knowing what to expect.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Let us know when the site is closed or quiet
- Name a contact who can let us in at the agreed time

There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, call us on 0345 646 2711 or drop us a line.

Common questions in Twineham Green
Is Twineham Green in your area for AHU cleaning?
Yes. Our area runs across London and the South East, Twineham Green included. Get in touch with the details and we’ll arrange a survey.
Will you come out to Twineham Green?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’re fully insured and have been trading since 2009.
What does AHU cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before work begins.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. We’ll tell you after the survey whether the ducts need it.
Which sectors do you work in?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
What do you clean inside the unit?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Keep the certificate and photo report with the plant records
- Plan the next inspection before the last report gets filed away
- Make sure the unit’s access doors open easily
- Note any water around the unit or leaks below it
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.

Other services in Twineham Green
Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Do you need AHU cleaning in Twineham Green?
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and that’s where slime and odours start.
These are the problems we see most often:
- Filters that are clogged or overdue
- Plant that needs cleaning after a refit
- Dust built up on fan impellers
- Blocked condensate drains and slimy trays
Classrooms and halls at schools such as Twineham CofE Primary School are easiest to work in when pupils are away.
What your quote should include
- If they look at the system before pricing
- Whether the figure could change on the day
- Proof of accreditation you can verify
- How areas they can’t reach will be recorded
Different parts, different methods
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
